NativeScript 6.40 has a couple cool new things; but better yet it fixes several issues that can will affect your users if you are using 6.3.x lets look at them...

Some of the fixes include instability during android's fragment handling occurred in 6.32, which is worth while. A couple really awesome community PR's, and of course one of my favorite items is the new CSS parser by default and the v8 upgrades...

[UPDATE] The new 6.4.1 Android engine that was just released a day or so after 6.4.0 adds v8 version 8! Which add a lot of cool features (see v8 section)

Core Modules

NativeScript is got a new much faster CSS parser in v6.3 -- it is now default in 6.4!

The community (Ryan & Hamdi) and the NativeScript team worked on 3d rotation for a while now; this has now shipped! .rotate-x, .rotate-y, and .rotate-z

.Fixed background color reset on Tabs

We had even more awesome community PR's this month, a big thank you to the community!

Webpack Changes

V8

If you didn't read my notice on the last update; I'm creating this new v8 Section, because Android and soon iOS will both be using the same v8 engine. v8 was upgraded to v7.9 (in 6.4.0) and then the awesome v8.0 was slipped into (6.4.1) which adds:

IC Handlers are now cached properly; giving a ~12% for all IC calls into the C++ runtime.

OSR Replacement - 5% - 18% speed up.

Pointer Compression (Saves up to 40% of heap memory) which increased speed on large JS by a few percentage points!

Optional Chaining

Null coalescing

Android

Async WebAssembly issue resolved

Memory freed on some objects that were being retained

Upgraded to V8 8.0 (See v8 section)

Fix for Elevation usage on some API versions

"FlipRight/flipLeft" transition fixed

IOS

The CLI will warn you if you forget a module.modulemap file in your included .M files

Project Template is FastLane compatible

Fixed discarded exceptions

Safari Inspector now shows startup errors

A lot more changes to the new v8 version of the iOS runtime that is now in BETA testing to eventually replace the JSCore version... Overall now is the time to test it!
